<p>PURPOSE:To make the fixing work of spray nozzle to a spray piping as well as the exchanging work to be easy by providing L-shaped cutting parts to the top end of the spray piping and fitting the protruded parts of nozzle sleeve of spray nozzle with the cutting parts. CONSTITUTION:A seal ring 28 is furnished in the seal ring inserting groove 30 in the nozzle sleeve 26, which is inserted into the spray piping 9 with the protruded parts 27 of the nozzle sleeve 26 along the cutting parts 25a of the spray piping 9. The nozzle sleeve 2b is rotated along the L-shaped cutting parts 25b to engage the protruded parts 27 with the cutting parts 25b. Then, a fixing screw 27 is inserted into the recessed part 31 provided in the nozzle sleeve 2b to prevent the spray nozzle 10 from rotating. Thus, the spray nozzle 10 is surely supported. By this method, the man-hour of fixing and exchanging is saved.</p> |
